struct InformationCache

Declaration

struct InformationCache { /* full declaration omitted */ };

Description

Data structure to hold cached (LLVM-IR) information. All attributes are given an InformationCache object at creation time to avoid inspection of the IR by all of them individually. This default InformationCache will hold information required by 'default' attributes, thus the ones deduced when Attributor::identifyDefaultAbstractAttributes(..) is called. If custom abstract attributes, registered manually through Attributor::registerAA(...), need more information, especially if it is not reusable, it is advised to inherit from the InformationCache and cast the instance down in the abstract attributes.
